Irwin 6X Blue Groove Wood Drill Bit

The Irwin 6X Blue Groove 16mm Wood Drill Bit is perfectly sized for medium-diameter drilling applications in timber, making it ideal for creating holes for pipework, cable runs, and general joinery work. This 16mm variant offers an excellent balance between versatility and precision, suitable for both site work and workshop applications. Designed specifically for wood drilling, this bit delivers six times faster drilling penetration than a standard flat bit, dramatically reducing work time on repetitive tasks. The advanced Tri-Flute design ensures rapid chip ejection, preventing clogging and maintaining consistent performance throughout deep holes. A full screw tip provides positive engagement and effortless pull-through, whilst precision-ground cutting spurs create professionally clean holes with minimal breakout. The tapered flute geometry reduces binding during operation, allowing smooth, controlled drilling even in dense hardwoods. Heat-treated construction ensures this 16mm drill bit maintains its cutting edge and delivers reliable performance over extended professional use.
